According to the Jefferson Parish Sheriff's Office, 58-year-old Terrill Normand was found close to the scene of the fire and taken into custody.

Normand invoked his right to an attorney, officials said.

According to investigators, Normand had an infatuation with one of the victims. Evidence was found near the scene, linking Normand to the investigation.

The fire broke out around 2:48 a.m. Tuesday in the 2300 block of Harvard Avenue. That is near the Jefferson Parish Public Library on West Napoleon Avenue.

At least four apartments suffered fire damage. Neighbors said one person broke his leg escaping through a window but was still able to help other residents escape from their apartments.

When firefighters arrived at the scene and extinguished the blaze, three bodies were found inside. The names of those killed have not been released. However, authorities did say that the victims were a white woman in her early 40s, a white man in his early 30s and another white man in his late 50s.

Based on the initial findings by JPSO detectives, an accelerant was detected by the JPFD and LA State Fire Marshal's Office.
